PAT Testing for Construction Sites — What You Need to Know

PAT testing for construction sites explained. What is required, how often to test, and what it costs. Professional PAT testing from Green Tag.

Construction sites are high-risk environments for electrical safety. Power tools, extension leads, and temporary equipment are subject to extreme wear. The IET Code of Practice recommends PAT testing every 3 months.

What Appliances Need Testing in a Construction Site?

Any portable electrical appliance that has a plug needs PAT testing. In a typical construction site, this includes:

  • Kettles, microwaves, and kitchen appliances
  • Computers, monitors, and printers
  • Phone chargers and extension leads
  • Heaters and fans
  • Any specialist equipment with a plug

How Often Should a Construction Site Be PAT Tested?

The IET Code of Practice provides guidance on testing frequency based on the type of equipment and the environment. For most construction sites, annual testing is recommended. Higher-risk environments may require testing every 3–6 months.

Is PAT Testing a Legal Requirement for Construction Sites?

There is no single law that mandates PAT testing by name. However, the Electricity at Work Regulations 1989 and the Health and Safety at Work Act 1974 require that all electrical equipment is maintained in a safe condition. PAT testing is the recognised way to demonstrate compliance.

What Happens During a PAT Test?

Each appliance undergoes a visual inspection followed by electronic testing using calibrated equipment. We check for damage, measure earth continuity and insulation resistance, and verify the appliance is safe. Appliances that pass are labelled with a test date and next test due date.
